Current River Flow Updates

Latest update: 7/3/2020 -- Flows are at 103 cfs in Silverthorne. Below Dillon the Blue has returned to its normal flows that we're used to for a majority of the year. Dry dropper fishing is going to be the most productive method to fish the town section with a stimulator on top and a midge or baetis pattern bellow. Smaller tippet such as 4x to the dry and 5x to nymphs. Besides mysis try- worms and eggs, then midge and baetis patterns sizes 18-22. Water north of Silverthorne is still looking good. Out of town use- Stoneflies, Egg patterns, worms, small mayfly and midge patters.

River Information

The Blue River through Silverthorne offers anglers the opportunity to catch a 20" trout in the morning and then shop at the Gap in the afternoon. While it may seem strange to park in an outlet mall's parking lot and get wadered up next to a family looking for some afternoon shopping, the fish that reside here can quickly refocus that distraction. This stretch of river sees considerable pressure, however the fish typically respond favorably to a good dead drift. Sight fishing opportunities are abound here and the fish are typically very aesthetically pleasing in coloration and size due to the protein rich diet provided by the dam of Dillon Reservoir.

Seasonal Conditions

In true tailwater fashion, the flies you need to catch fish here are typically the same year round. Nymphing will be the rule throughout the majority of the year, however some good summer dry fly fishing can exist given the right conditions. Midges, Baetis, Caddis and the ever aesthetically Mysis Shrimp should be your focus. Small streamers can also be protein-rich during the low light hours. This river is fishable year round and sees no shortage of anglers.
